System Board
The Input/Output Controller Hub 2 (82801BA)
Chapter 2
53
The Input/Output Controller Hub 2 (82801BA)
The ICH2 is encapsulated in a 360-pin Enhanced Ball Grid Array
(EBGA) package and resides on the system board just underneath the
AGP connector. It provides the interface between the PCI bridge (PCI 2.2
compliant with support for 32-bit 33MHz PCI operations),
PCI-to-Low Pin Count (LPC) bridge, IDE controller, USB controller,
SMBus controller, and Audio Codec’97 controller.
You’ll find more detail about the ICH2 functions and capabilities later in
this section. Figure 2-8 shows an example of the system block diagram
using the ICH2.
